Type
Operation
When normal utility-supplied power is present, the LSN model central lighting inverter
provides load-side line conditioning with "brownout" protection, and charges the system
batteries when required. When utility-supplied power is interrupted, or the voltage varies
from predetermined limits, the system will automatically and instantaneously transfer to
emergency mode without interruption to connected loads. DC battery-derived emergency
power is inverted to AC power and supplied in a pure sine wave output form for 90 minutes
(standard run time). A low voltage battery disconnect circuit prevents “deep discharge”
damage to the batteries during prolonged power outages. When normal power is restored
the system will automatically restart, providing power to connected loads and recharging
the batteries. The charging circuit will bring the batteries to full recharge within UL time
standards.
Construction
The LSN cabinet is constructed of steel, finished with a light gray paint and features
locking cabinetry and password-protected user interface for security. Louvers at front
and top of cabinet allow venting.
